My invention relates to delivery mech'anisms for newspaper stufling or similar machines; particularly meohanislns in which newspapers or other articles are ream the bottom of apile so that theyma-y be removed manually or otherwise froin the top of the pile." 7

I V of the inventionis to provide a simple and practical delivery mechanism of the class specified.

Another object of the invention is to secure quickness and elfectiveness of operation.

Another object of the invention is to assure proper piling of the papers or articles and all" to prevent interference of the papers one with another and also. to prevent lthe papers from being; (jammed or creased or improperly nism';

folded. I I V In the accompanying draw ngs F g. 11s a plan view of adelivery mechanism embodying my present invention 5 Fig. 2 is an end elevation'of the same; Figs. 3 and l are vertical sections taken on lines 3+3 and le l respectively, in 1'; Figs. '5 and'6 are crosssectional views of details of construction; I 1 Fig. 7 is a crosssection'taken on line 7-"-7 inFigfil; i g r Fig. 8 is a front elevation of the inecha- Figsj'9 to 16, inclusive, 'are'views of details of construction.

Referring to the drawings, I show a delivery mechanism for piling and delivering newspapers, so that the newspapers maybe introduced or inserted-into the pile at the bottom thereof and oontinuallypushed upwardly so 'thattheymeybe taken oifljfrom the prising a plu i y of secti ns-arepu ogether p 7 top. Thismechanisn is particularly adapt- 1 ed "for usein connection with newspaper stuifing n ach-ines'm' wh ch newspapers com? or stuffed, as it is called, bythe'insertion or introduction of one or more sect ons orperts into another'section or part-which is Loallledthe cover section. It will be apparent thatthe 'niechanism can be used for other purposes.

Referring first-to Figs. 1, 3 and 8, I show a body frame having an. upright l l which ma fbes'u tably mountedion a floor or otherwise;

also ,a hopper member '2 in front oi? the-body member '1. The member 2 'has'a'hopper 3 into which the articles-to be piled and delivered are fed. .Inthe vstuffing machine the completecl newspapers are preferably fed to the deliverynieclianisin in an uprightcondition V the inner or insert sections being introduced or s tufied'in'to the cover section :most con venlently in such vertical condition. In Figs. 1 and 7 a completed newspaper "A -is immediately adjoining the delivery mes-ha nism. set forth herein.

late 15 being to act againstthe side of the newspaper and arranged-to swing so as to move and li'frtthepaper from "a'vertc'al to a horizon-pal position. The hooks lGengage o thelow ir-or toldeded e,orth a r-asshole it i rippe .pe t on' d r n i d swinging1novement,as shown-in '17,,1the member" 2 hevinga' curved surfaeelfi corre sponding substantially with the curve --macle by the folded edge of the newspaper as it is swung'upwardly. i

The actuating plate with its hooked member 16 is operated by suitable mechanism to give it the requisite swinging movement. This mechanismcomprises a swinging arm 19 pivotally connected at 20 to the back of the plate 15. The arm 19 is pivotally mounted on shaft 21 which latter is supported in bearings on the main frame 1. Said arm '19 is actuated. by a reciprocating link 22 pivoted to the arm at 23, the link 22 having bifurcated end portions 24 to straddle the arm 19 and engage the pin 23. There are two side arms .9 similar to arm 19. The link 22 is' con nected at 25 to a rotary wheel 26 so that the. rotation ofthe wheel 26 will actuate the link V 22 to swing the arm 19 backwardly and forwardly-to lift a paper A into horizontal position and thento retract and come into position to engage another paper in verticalposition and swing the same into horizontal'position. The wheel 26 is mounted on a shaft 27 mounted in bearings 2828 (Fig. 1)..

The abutment 12 is mounted so that it can be'moved into and out of the path of'travel of the newspaper A, so that said papers may be pushed upbeyond said abutment and then rest'on the same. As a simple arrangement aid abutment 12 is formed as part of a swinging member 30 pivoted at31 and subject to a spring 82 tending to swing said memberinwardly. Said membe'rBO is provided with an inclined surface 33 against which the newspapers or other articles will strike and an abutment or stop 34 is arranged opposite the lower end of the member 33 to engage the lower end of the member 30 and prevent the same swinging unduly inward. Thus when 1 newspaper is swung up by the swinging member or platen 15, the outer or folded end of said newspaper will strike against and slide along the inclined surface 33 thereby pushing member 30 outwardly against the ac-. tion of spring 32 and permitting the news? paper being swung upwardly to pass above abutment l2 formedon member 30. After passing above said abutment 12, member 30 will swing back inwardly,thereby permitting abutment 12 to come into position underneath the outer or folded edge of said paper which thereupon rests upon said abutment so that the latter serves to support the pile of papers. After the member 30 swings backinwardly to place the abutment 12 in supporting position platen 15 is retracted so as to move into. its downward positionto act upon another paper.

Abutment 13 is held in position by the frame ofthe machine, as for example, by being bolted by means of bolt 35 to downwardly projecting lug or bracket 86. Said abutment 13 has an inclined surface 37 and a finger 38 extending downwardly and then slightly inwardly and. positioned and arranged so as to cooperate with the upper end ofthe platen 15. v

Thus the end of the platen 15 slides along the finger 3'8 and inclined surface 37 as said platen is swung upwardly to raise a newspaper, the result of which is that the newspaper will. be moved so that its inner orunfolded end will come into position upon the top ofabutment 13 when platen 15 is in substantially horizontal position, as shown in Fig. 3.

In order'to lift thepile .sufiiciently to permit each additional paper to come inte position aboveabutment 13, means'are provided for lifting the'pile just prior to the insertion of each paper above said abutment. As one arrangement for accomplishing this, I show a lifting device 40 having three lifting members or fingers 4141, said member 40 being mounted on a rock shaft 42, which is in turn supported by bearings 43 and is given acertain amount of'up and down movement, so that the members '41 may push against the lowermost paper in the pile andlift the same to permit the introduction of another paper, and may also be moved seas to withdraw from underneath the pile after the additional paper has been inserted, and permit the pile to rest on said additional paper. In Fig. 2 one of theiingers 41 is shown pushed upwardly against the lowermost one of a pile of papers to lift the same and allow the insertionof another paper below the pile, and in Fig. ,3 this additional paper is shown inserted in position below the pile and the arm 41 is about withdrawn so as to permit I the upper papers to settle and rest upon the new papers just inserted.

As an arrangement for actuating this member 40 in this way, the bearings 43 for the shaft 42 are mountedonthe arm 44 of a bell crank 45 mounted on a sleeve 45' which carries a floating shaft 46randanother arm 47, both 47 and 45 being pinned to 45. The arm 47 is actuated by connections with the rotary shaft 27. These connections comprise a yoke or cross head 48 mounted to slide on a bearing block 49 on shaft 27, said yoke being pivotally connected by a pin 50 with the lower end of arm 47. Yoke or cross head 48 carries two rollers 51 and 52, whereof the roller 51'is adapted to cooperate with'cam on shaft 27 and roller :52 is adapted to co operate with cam 54 on said shaft. By'this arrangement arm 47 is given a positive reciprocating motion by said cams so that the arm 44 will be raised and lowered to position lifting member 40 as required. The end of arm 44 is provided with rollers 44 (Figs. 7 and 11), along which the platen 15 will rollas y wheel 60. (Fig.2) mounted on shaft lo-which carriesgear .61 meshing'with gear 62, the

latter being on a shaft 63 which is wider stood to 'be'the' main drive shaft of themachine. Thisgear 62 also nesheswitli a gear 64 on. shaft 27 so as to drive the latter and the meohanismoperated thereby. By sucharrangement gear 63 ;reciprocates link 57 and thereby causes the projecting arms or fingers ll to swing about the shaft 4221s required, while at the same time this shaft '52 is'raised and lowered by rocking movement of bell crank arm 44, as previously described. Movement is imparted to member 40 by rocking of shaft 42'by means of ratchet'mech-anismcomprisinga spring controlled dog 'cooperating'with a toothed wheel 66 onfthe shafttQ', so that shaft eO'is rotated continuously 1n the directionindicated by 'arrow inFig. 2. Dog 65 is supported-and mounted by pivot-68 on arm 59 whichiin turn is sup portedcn arm 57. An annular-member 69 is pivotally connected at 70 tolink 71 mountedRonLshaft'ZQ, so thatfup and down movement of shaft- 42 maybe taken care of at the same time thatrockerarm 59 is being actuaitedby linkw57. A ring 73 of friction materia-l'is provided within bracket ring-'69 cooperating with friction members 74 to-insure proper action of the ratchet mechanism.

. Shaft l2 is held in position for operation of arms 41 by recesses 4E2 in collar 42? on shaft 42 and roller 42 on arm 42?, (Fig. Spring 42 attached-to arm l2 holds roller 42 in said recesses 42 As .a preferred arrangement provision is made for indicating the numberof' papers stacked in the pile. To such end provision is made so that certain papers maybe pro-- jBCtGCl beyond the others, the'p'rojecting p a-.

persbeing apredetermined "number of papers apart For example, as shown in Fig. '8,

papers A" are projected beyond the others. The papers A. may beevery fifth, tenth or other paperas desired. As arranged'they are twelvepapers apart so that each one indicates a dozen papers in thepile. I

To such end av platen or. abutment member 75 is arranged at one end of the chamber or ere space 3' (Fig. 2), so'that the papers fed into the space 3 will strike against said' member 7 5., and provision is made for rmoving this member 75 outwardly at a predeterminedtime .to permit one newspaper to be advanced tun Thor than the others, whereby thisone news- I paper will become a paper A'f'which projects beyond the others.

Asan arrangement forautomatically moving the member 75 outwardly at predetermined intervals and returning'itfor intervening periods of time, saidplate 7 5 is shown mounted ona swinging arm 76 which latter is mounted on a verticalrock shaft 77 supported in-b e-arinlgs .78. Said shaft ,7Zal's0 carries an arm 79 liavi-ng its onter 'end-provided with a roller 80 which latter travelson a circular r-aee'81, -Wh10l11't06, however, has area'r-m' 'Z'Q -and .whien rollerrSO and recess 82 come together, said roller will fall :into. said recess and therebypermit spring 83?.to-pullarm inwardly and thereby swing the arm 76 10utcessl'82 into: which the :roller 80- may .move. Aspring-83, (Fig.5) normally pulls upon wardly and withdraw :plate75 a small distance, as indicatr-id in 'dotted'lines in Fig. .5.

Theretoreia paper fed flIItO'tllG hopper 83' at a time when fmember 75 is withdr awn. will be displaced zrelatively to theposition of the other papers as previously described. The annular race f il is formed ona rotary'wheel' 85 which ismountedon-shaft -86-Which latter is provided with ratchet mechanismadapted to turn shaf-t 86 inla stepbystepmovement V WillCl-PlS arrangedto bringthe ;-recess82.into f mechanism show-n comprises a dog 87: carried on an ar1n 8j8 pivotaliy connected with the lowerend 'of alin-k'89 (Fig.4) ,:Which link 89 is connected with a cross headtQOmounted on cam 91 carr-ied on shaft 46. Thusrotation off the shaft #ltiwill cause reciprocation of linl; -89 and, actuationof ratchet mechanism to intermittently"turnWheel 85 andrthereby, through re'eess82 and wheel 80 allow spring 8-3to swing-arm 76 andretract platen 75 and thereby allowcne paper to .be advanced be.- yond the others.
